I know I might get some flak for this, but I was just curious about this debate so decided to check out the olympus site.

I know it's not FF, but if the logic is that bigger sensors mean bigger lenses, then it should also be concluded that aps-c lenses will be bigger/heavier than m43.

But after checking the olympus site, their equivalent lenses are heavier. They don't have exact same focal lengths but relatively close.

zuiko 14-54 2.8-3.5 = 440g

fuji 18-55 2.8-4 = 310

zuiko 50-200 2.8-3.5 = 995g

fuji 55-200 2.8-4 = 580g

These 2 Zuiko lenses are Four Thirds, NOT micro four thirds. They are a telecentric design which IS larger.

Micro four thirds lenses do not use the same telecentric design, so you should use MFT lenses in your comparison. The closest of which would be the Panasonic 12-35mm f2.8 at 305g, and the 35-100mm f2.8 at 360g.
